Background summary
For the vast majority of patients diagnosed with recurrent/metastatic cervical
cancer (r/mCC), platinum-based chemotherapy regimens were the 1L standard of
care for many years. More recently, a systemic combination therapy of
bevacizumab with either cisplatin+paclitaxel or paclitaxel+topotecan was
established as the standard of care for 1L treatment of patients with
persistent, r/mCC based on the Gynecologic Oncology Group (GOG) 240 trial. The
addition of bevacizumab to chemotherapy was associated with an increased
incidence of hypertension of grade 2 or higher (25% vs. 2%), thromboembolic
events of grade 3 or higher (8% vs. 1%), and gastrointestinal fistulas of grade
3 or higher (3% vs. 0%). This regimen is the standard of care for the 1L
treatment of r/mCC for patients who are eligible to receive bevacizumab.
Treatment options after the 1L are limited, and no standard of care therapies
have been identified.
Tisotumab vedotin binds to TF-expressing tumor cells, followed by
internalization of the ADC-TF complex, and the local release of MMAE via
proteolytic cleavage. MMAE disrupts the microtubule network of actively
dividing cells, leading to cell cycle arrest and apoptotic cell death. Released
MMAE can diffuse out of the cell into the tumor microenvironment and enter
neighboring cells by passive diffusion. If the neighboring cell is undergoing
active cell division, then MMAE can once again induce cell cycle arrest and
apoptotic death-a process called bystander cytotoxicity-independent of the
neighboring cell*s TF expression level. The direct cytotoxicity of Tisotumab
vedotin may be augmented by the immune-mediated tumor cell killing effects of
antibody-dependent cell-mediated cytotoxicity, antibody-dependent cellular
phagocytosis, and immunogenic cell death clinic. Finally, in vivo anti-tumor
activity of tisotumab vedotin was demonstrated in multiple tumor types in mouse
efficacy models implanted with cell line-derived and patient-derived tumor
xenografts.
Study objective
The purpose of this study is to demonstrate improvement in clinical efficacy of
tisotumab vedotin compared to chemotherapy in participants with second- or
third-line (2L-3L) cervical cancer (Overall Survival-OS)
Study design
This is an open-label, randomized (1:1), global, phase 3 study of tisotumab
vedotin versus investigator*s choice of chemotherapy in participants with r/mCC
who have received 1 or 2 prior lines of systemic therapy for their recurrent or
metastatic disease. Eligible participants will be randomized to either
tisotumab vedotin 2.0 mg/kg Q3W or investigator*s choice of chemotherapy (See
protocol section 4.3).

Study burden and risks
For the Investigational product - Tisotumab Vedotin, Subjects should come to
the study center every 21 days for infusion administration and blood draw
controls. every 6 weeks a CT scan should be made to monitor tumor development.
The administered medication also has a chance of side effects as described in
detail in the test subject information. In view of the prognosis for this group
of subjects and the group that has already been extensively treated, the burden
in relation to the expected outcome is acceptable.

Inclusion criteria
1.Age >=18 years , or considered an adult by local regulations, at time of
consent.
Has recurrent or metastatic cervical cancer with squamous cell, adenocarcinoma,
or adenosquamous histology and:
Has experienced disease progression during or after treatment with a standard
of care systemic chemotherapy doublet, or platinum-based therapy (if eligible),
defined as either:
paclitaxel+cisplatin+bevacizumab, or + anti-PD-(L)1 agent
paclitaxel+carboplatin+bevacizumab, or + anti-PD-(L)1 agent
paclitaxel+topotecan/nogitecan+bevacizumab + anti-PD-(L)1 agent
2. Has ECOG performance status of 0 or 1 prior to randomization.
3. Has life expectancy of at least 3 months.
4. Has a negative serum pregnancy test for participants of reproductive
potential. Participants that are postmenopausal, permanently sterilized or
previously subjected to bilateral oophorectomy, bilateral salpingectomy and/or
hysterectomy can be considered as not having reproductive potential (refer to
Section 10.4 of protocol).
5. Participants of reproductive potential must agree to use adequate
contraception during and for 6 months after the last study treatment
administration. Adequate contraception is defined as highly effective methods
of contraception (refer to Section 10.4 of protocol). Two highly effective
methods of contraception must be used in countries where this is required.
6. Must agree not to breastfeed or donate ova, starting at the time of informed
consent and continuing through 6 months after receiving the last dose of study
drug administration
7. Where required by local health authorities, has negative serology for
hepatitis B surface antigen (HBsAg)/HBV DNA, or hepatitis C antibody (HCVAb) or
RNA. Active hepatitis C is defined by a known positive HCVAb result and known
quantitative HCV RNA results greater than the lower limits of detection of the
assay.
8. Must be able to provide tumor tissue. The most recent archival tumor biopsy
is preferred if collected within the last 2 years. If an archival tumor biopsy
less than 2 years old is not available, a fresh tumor biopsy will be collected
before initiation of study treatment, if clinically feasible. If a fresh biopsy
cannot be collected, the most recent archival tumor sample may be submitted,
even if obtained more than 2 years prior to participant enrollment.
9. Must be willing and able to adhere to the prohibitions and restrictions
specified in this protocol.
